A trailer (also known as a preview or upcoming attraction) is a commercial advertisement for a feature film that will be presented in a cinema exhibition in the future, a result of creative and technical work. The term “trailer” refers to the distribution of films on film trains. The reels were always divided into rounds (they had to revert to the theatre to show the film, as the initial experience showed the danger of coming back to the film). So, the most enduring part of the film was the preview, which was trimmed, leaving the film “retreating.”
Movie trailers have now become popular on the Internet and mobile devices in addition to DVDs and Blu-ray discs. Out of the 10 billion videos watched online every year, movie trailers rank third after news and user-generated videos.  The trailer has also been adopted as a promotional tool for television shows, video games, books, and theatre programs/concerts.
